Product Description


Input voltage

4.5-8V

Static current

0.5 mA

Overshoot protection

Yes

Size

3.3X2.3X0.9

Output reference maximum current

5V 1.4A , 9V 0.8A, 12V 0.6A

Discharge current

max 2A output current to calculate

All circuits are connected and then connected to the battery.

Before use, before debugging, the default output is about 9V.

Input voltage 4.5-8V

The output voltage can be continuously adjusted by 4.3-27V (4.3V or more and 27V or less. Any voltage can be output, and the voltage can be adjusted counterclockwise.)

Charging voltage 4.2V Charging current Max 1A

Discharge current maximum 2A output current to calculate

Output reference maximum current 5V 1.4A , 9V 0.8A, 12V 0.6A

Static current is about 0.5 mA

Overshoot protection

Over-discharge protection None (it can be said that there is 2V cut-off boost but does not block the output output or 2V)

Cut-off boost 2V, depending on the situation, whether to add a protection board

Size 3.3X2.3X0.9

For example, VIN+ termination 5V solar panel BAT+ terminal can output 4.2V to charge 3.7V 18650 battery

OUT+ terminal can output an adjustable voltage.

Can be used for multimeters, modified lithium battery charging
